Description

[Detailed Description of the Invention] The present invention relates to a heating plate mounting device for a rice cooker with a gas jar that absorbs heat from a burner and conducts the heat to a rice cooking pot.

In a gas rice cooker, when the flame from the burner is not applied directly to the bottom of the rice cooker, but is heated via the hot plate, the hot plate has a large temperature difference, so the hot plate is mechanically fixed to the inner case of the rice cooker. Internal stress is generated in the hot plate, which causes distortion when the temperature reaches high temperatures.

This invention is a mechanical coupling means to connect the inner case and the hot plate of a gas rice cooker so that the hot plate will not be distorted even if there is a large temperature difference at the bottom, but there is a certain amount of play between the inner case and the hot plate. The object of the present invention is to obtain a heating plate mounting device for a rice cooker with a gas jar that is combined in such a manner that the

The present invention will be explained based on the drawings.

shows.

In the figure, 1 is the inner case of the rice cooker, 2 is the insulation material required for keeping warm, 3 is the exterior of the rice cooker, 4 is the gas burner for cooking rice, 5 is the heat plate that absorbs the heat of the gas burner 4, and 6 is the heat plate that absorbs the heat of the rice cooker. Pan, 7 indicates a thermostat.

The hot plate 5 serves to absorb the heat of the gas burner 4 and transmit the heat to all sides.

The inner case 1 has an annular bottom 1 protruding inward at its lower periphery.
-1 is provided, and the tip is bent downward to form a hanging part 1-2.

Three or four concave cutouts G having intervals α are provided at equal intervals on the bottom part 1-1, and a claw part P that projects obliquely integrally with the inner case 1 is provided in the center of the cutout part G. .

On the other hand, a U-shaped claw portion that integrally protrudes from the peripheral edge of the hot plate 5 can be inserted into the cutout G of the bottom 1-1.1-2 of the inner case 1, and opens outward. The size of the claws in the shape is such that the hanging part 1-2 can be inserted into the U-shaped recess 5-1, the number of claws is the same as the number of claws P, and the positions provided on the periphery are in the claws P. Set the corresponding position.

Next, the order of joining the inner case and the hot plate will be explained.

When the claws of the hot plate 5 are inserted into the cutouts G from above, the claws P provided in the cutouts G are pushed and bent by the lower ribs 1 of the claws as shown in FIG. The hanging part 1-2 is fitted into the cutout part G with the hanging part 1-2 inserted into the recessed part of the claw part, and the installation is completed by rotating the hot plate 5 in either the left or right direction in this state.

When the attachment is completed, the pressed and bent claws P return to their original shape, and the claws P of the hot plate 5 act as a stopper, and cannot be removed from the cutout G in this state.

FIG. 4 shows a sectional view of the removed portion of the hot plate 5 attached to the bottom of the inner case 1.

Since the present invention has the above-mentioned configuration, the heating plate can be easily fixed to the inner case, and it can sufficiently absorb thermal expansion without causing thermal deformation to have an appropriate amount of play.
Even if the heating plate is placed upside down (for example, during cleaning), there is no risk of the heating plate falling and it is safe.
